VQ37VHR
It was the first production engine from Nissan using VVEL. It has an increased compression ratio of 11.0:1, with 3,696 cc (225.5 cu in) displacement (95.5 mm bore and 86 mm stroke), while redline remains at 7600 rpm. It is rated at up to 337 PS (248 kW; 332 hp) at 7,000 rpm and 37.2 kg·m (365 N·m; 269 lb·ft) at 5200 rpm. Although the engine gains only 0.2 kg·m (2 N·m; 1 lb·ft) peak torque over the VQ35HR and this higher torque arrives at 5200 rpm vs. 4800 in the VQ35HR, the torque curve itself is improved and flattened via VVEL variable valve timing for better throttle response and low rpm torque. The VQ37VHR engine has been touted by car magazines and reviewers as an improvement over the VQ35HR engine mostly adding much refinement and smoother engine operation, especially at high rpm where the VQ35HR engine was frequently criticized for NVH and sounding strained, harsh and loud.
